Native iOS apps built in Swift and SwiftUI
Swift is the right choice when your product lives on iPhone first and depends on what the platform does best: smooth interfaces, background tasks, Bluetooth, location, health data, widgets and in-app purchases. Our team writes modern Swift with SwiftUI for the interface and drops into UIKit only where it still earns its place. We also publish and maintain our own iOS apps on the App Store, so the review process, StoreKit edge cases and OS updates are part of our daily work rather than something we read about.
What we deliver
SwiftUI interfaces
Screens built with SwiftUI, a clear navigation model and design tokens, with Dynamic Type, dark mode and VoiceOver handled from the first build.
Apple framework integrations
HealthKit, MapKit and Core Location, Core Bluetooth, Vision and VisionKit, PDFKit, CallKit extensions and push notifications, wired in with the right permissions copy.
Subscriptions and purchases
StoreKit 2 paywalls, free trials, introductory offers and receipt validation, with server-side checks where revenue depends on it.
Widgets and extensions
Home and Lock Screen widgets, Live Activities, share extensions and App Intents for Siri and Shortcuts when they add real value.
Architecture and tests
A modular project using Swift concurrency, dependency injection and unit and UI tests, so new developers can work in it without guesswork.
How we approach it
When Swift is the right call
Choose native Swift if iOS is your primary market, your app relies on hardware or system features, or premium feel is part of the product. If you need Android at launch on a tight budget, we will say so and compare Flutter honestly.
SwiftUI first, UIKit where needed
SwiftUI speeds up interface work and keeps code readable. For complex text editing, camera pipelines or older OS targets we use UIKit components behind a SwiftUI wrapper.
Trade-offs stated upfront
A native iOS app means a separate codebase for Android later. We structure the backend and API so a Kotlin or cross-platform client can be added without reworking the product.

Built by our team
Our own native iOS apps use maps and routing, AirPrint and document scanning, and Bluetooth signal scanning.
How we work
- 01
Discovery
A short call to understand your goals, users and constraints. You get a clear scope, timeline and estimate.
- 02
Design
User flows and high-fidelity screens that follow Apple’s Human Interface Guidelines — reviewed together before a line of code.
- 03
Build
Iterative development in Swift and SwiftUI with regular TestFlight builds, so you can try the app on your own iPhone as it grows.
- 04
Launch
App Store assets, submission and review handled end to end. Your app goes live under your own developer account.
- 05
Support
Bug fixes, iOS version updates and new features after launch — based on real user feedback and analytics.
Questions
Swift or Flutter for a startup?
If your users are mostly on iPhone, or the product depends on Bluetooth, health data, widgets or background location, Swift gives a better result. If you must launch on iOS and Android at once with one budget, Flutter is often the more practical start. We recommend one after the discovery call.
Do you still use UIKit?
Yes, selectively. New screens are built in SwiftUI, but we use UIKit for parts SwiftUI still handles poorly, such as advanced text input or custom camera views, and when maintaining existing UIKit codebases.
Which iOS versions will my app support?
Usually the current and previous major iOS versions, which covers the large majority of active devices. Supporting older versions is possible but limits which SwiftUI features we can use, so we agree the target during discovery.
Can you take over an existing Swift codebase?
Yes. We start with a code review to assess architecture, dependencies and crash reports, then propose a plan to stabilise and extend the app rather than rewrite it by default.
Will the app publish under my Apple developer account?
Yes. The app is published under your own App Store Connect account and you own the full source code. We handle signing, TestFlight builds and the review submission with you.
